  • Publication number: 20200103323
    Abstract: A system for comparative pressure measurement includes a measuring chamber filled with a gas mixture having a gas pressure. A first sensor is arranged in the measuring chamber. The first sensor is adapted to measure the gas pressure independently of a type of the gas mixture. A second sensor is arranged in the measuring chamber. The second sensor is adapted to measure the gas pressure based on a known dependency from a type of the gas mixture. An evaluation unit determines a state of the gas mixture based on the gas pressure values measured by the first pressure sensor and the second pressure sensor at the same time.

  • Patent number: 10481031
    Abstract: An improved Pirani sensor uses a measuring element disposed within a fluid between a base plate and a cover. The measuring element is held by suspension members that are connected to the base plate. A heating element is thermally conductively connected to the suspension members. Using the sensor the characteristic of the fluid is determined by evaluating the heat transfer from the thermal element through the fluid into the cover when heating power is applied to measuring element. Parasitic conductive heat loss from the measuring element into the suspension members is compensated by applying power to the heating element.

  • Patent number: 10436665
    Abstract: A method comprises suspending a measuring element within a fluid and applying measuring power to the measuring element. Radiation loss compensation power is applied to a heating element. The radiation loss compensation power is selected to compensate parasitic radiative heat loss from the measuring element. Heat transfer from the measuring element into the fluid is evaluated and a property of the fluid is derived. A sensor which implements the method uses a resistive measuring element which is electrically connected to an evaluation circuit. The heating element is electrically connected to a power source. A processor receives an input from the evaluation circuit and calculates a property of the fluid while the power source provides radiation loss compensation power to the first heating element.

  • Publication number: 20190212219
    Abstract: To prevent negative influences of a measuring gas on vacuum sensor elements a protective device including one or more deflection elements made of wire, tape, or tube is inserted between the gas port or a vacuum measuring cell and the sensor element or sensor elements therein. The deflection element may be a spiral-shaped member and may be fabricated and deposited by laser melting from pure metal or an alloy on an inlet or outlet plate. The deflection element may react with the sample gas or its constituents. The deflection element extends the path of the incoming measurement gas to the sensor element and deflects the flow direction, whereby contaminant particles carried with the gas are deposited on the deflection element.

  • Patent number: 9976922
    Abstract: The disclosure relates to a pressure sensor for measuring a fluid pressure, in particular a vacuum pressure. The pressure sensor contains a first and a second diaphragm connected to one another such that they enclose and hermetically seal a fluid space. Fluid can enter and exit the fluid space through a fluid supply element, which is connected to an exterior opening of the sensor. Each of the diaphragms is proximal to a reference electrode and forms a variable capacitor, the capacitance of which depends on the position of the diaphragms, which in turn depends on the pressure in the fluid space.

  • Patent number: 8841115
    Abstract: The present disclosure describes use of filamentous algae to form insulating construction materials which provide thermal and noise insulation. Algae from the order Zygnematales, the Cladophorales, or the Ulotrichales can be dried and formed for use as insulating material. Algae mass can be combined into several layers, using a binder to attach the layers to each other. A composite material of algae mass and an additive can be used and form the body of insulation panels having honeycomb-shaped chambers, which are sealed by a foil that is laminated onto the body.

  • Patent number: 8047711
    Abstract: A thermocouple vacuum sensor is provided, the thermocouple being surrounded by a gas or mixture of gases the pressure of which is to be measured. Cyclically the thermocouple is heated until its temperature reaches an upper temperature threshold. The thermocouple is subsequently cooled until its temperature reaches a lower temperature threshold. The heating time required to heat the thermocouple from the lower to the upper temperature threshold is measured. The cooling time required to cool the thermocouple from the upper temperature threshold to the lower temperature threshold may also be measured. The pressure surrounding the thermocouple may then be determined as a function of either the heating time, or the cooling time, or both.

  • Publication number: 20110167919
    Abstract: An interoperable vacuum measuring device is presented, which automatically adjusts to one of two or more vacuum sensors having different electrical characteristics. The interoperable vacuum measuring device in a first step detects which type of vacuum sensor it is connected to. In a second step it controls and evaluates the vacuum sensor, using control parameters determined in response to the detection of the first step. Detection of a vacuum sensor type is achieved by measuring the electrical resistance between any two pins of a vacuum sensor's connector and comparing the measured resistance values with stored resistance values of known vacuum sensors. Further, a vacuum measuring device is presented, which automatically identifies a vacuum sensor, and associates a vacuum pressure measurement with a vacuum sensor. The identification of a vacuum sensor is facilitated by an identification disk, which is placed onto and operatively connected to the male terminals of a vacuum sensor's connector.

  • Patent number: 7497118
    Abstract: The invention relates to construction principles, operating and manufacturing methods for inertial sensors, i.e., sensors for rapidly detecting movement and acceleration in all degrees of freedom in space, and for separately detecting the position with respect to the perpendicular under the action of acceleration due to gravity. Use is made of the knowledge that to maintain a common convection zone of two or more sensor elements, the power fractions supplied to these elements vary with change in position, movement and acceleration.
